While some modern houses scream high-tech, Harbour Hide does its best to blend into its surroundings. But rest assured, those familiar high-tech amenities can be found all throughout the staggered, round beach house. Android tablets in every room allow the homeowner to set the desired ambiance, mood, lighting, and temperature for each part of the home. The system also runs the extensive audio-visual entertainment setup, curtains and blinds, and, most impressively, it controls the electronic photochromic glass which can darken or lighten as the sunlight warrants. There is also a hidden, heated swimming pool (with an endless-lap jet stream current feature) with tablet-controlled hatch and temperature. The asking price is just over $6 million.
